GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 966) = 187404
GCD(388, 966) = ( 388 x 966 ) / 187404
= 388 / 966
= 388
Step2:
LCM(2, 556) = 556
GCD(2, 556) = ( 2 x 556 ) / 556
= 2 / 556
= 2
Step3:
LCM(2, 409) = 818
GCD(2, 409) = ( 2 x 409 ) / 818
= 2 / 409
= 2
So, Greatest Common Divisor of 388, 966, 556, 409 is 1
